LO020 4.0A 采购处理 (Unit 6)
6-5
MRP can create purchase requisitions automatically if the material master record has been
maintained accordingly. If a source list with a valid source of supply exists, the purchase
requisitions created are automatically assigned to this source of supply.
Purchase requisitions can be automatically converted to purchase orders if they are assigned to
a source of supply. The “Automatically generated purchase order” indicator must also be set in
the material master record and vendor master record.
In the purchase order, you can enter that you expect an order acknowledgement and/or shipping
notification from the vendor. If a shipping notification has been entered, you can enter the GR
posting with reference to it.
In evaluated receipt settlement (the ERS procedure), the vendor does not send us invoices.
Instead, the R/3 System creates the invoice from the data in the purchase order and the goods
receipt. You have to have the vendor’s permission to use the ERS procedure and it must be
allowed in the vendor master record.
